June Sucker
This long-lived Utah Lake endemic survives through coordinated habitat restoration, captive propagation, flow management, and reconnection to tributaries.
Artwork inspired by John Hafen
June Suckers evolved only in Utah Lake and its tributaries. Adults feed in the lake and migrate into flowing water to spawn; altered river channels, invasive fish, drought, and lost nursery habitat drove collapse despite the species’ longevity.
Most people will understand the species through habitat and recovery work rather than a direct sighting. Watch public river restoration from established paths, never enter closed spawning areas, and do not confuse agency-handled fish with an invitation to capture them.

Observe June Sucker on its terms
- Body and pattern
- Look for soft terminal mouth, broad head, and little-branched lip structure when identifying June Sucker.
- Confirm the water
- Check spring spawning migration together with spring flows cue tributary movement before accepting the identification.
- Range matters
- Use Utah Lake and connected spawning tributaries in Utah Lake and tributaries.
- Protect the stream
- Rely on public river overlooks during spawning season and remain outside signed restoration or fish-handling areas.
Good to know
Recovery numbers can improve while the ecosystem remains fragile. Captive propagation is only one tool; functioning tributaries, floodplain nurseries, water quality, and control of predatory nonnative fish determine whether wild recruitment persists.
